Abstract: A system and method for alerting a driver to the presence of an EM signal from a police speed sensor signals (RADAR/LADAR), emergency vehicle signals and traffic hazard warning signals using RADAR/LADAR detectors and coupled GPS positioning system an transceiver. The system receives electromagnetic signal emissions and records the location of the Signal, providing that information to a central processor. A GPS system constantly updates the vehicle position so that the processor can note the vehicle position at the time the Signal was received. The GPS position signal is reformatted and broadcast to other vehicles having similar units. When a position signal is received by the transceiver, it is stored and compared to the present position of the driver's vehicle.
